On Cold War camera: 1950s Berlin in color (part 1) article (120 comments in total)

If you want some more interesting history on the recovery of the city, read about Teufelsberg: The "listening post" shown in one of the pictures was built in 1972. Ironically, abandoned, it is slowly becoming more of the rubbish comprising the hill.

Because West Berlin was surrounded by the wall, it became very difficult to deal with garbage disposal. The solution was to bulldoze it into higher and higher mounds. When a mound got big enough, it was landscaped and turned into a park. These mounds were built up near Teufelsberg itself, eventually creating a manmade range of hills in what is an ancient sea bottom, and otherwise very flat.

I was unable to travel to the Russian sector due to security issues, but friends who went there to shop and tour on weekends said that (as of the early 1970s) there were still whole city blocks of WWII rubble in East Berlin. By then, W. Berlin was a bustling Weldstadt, as it was viewed then.

d7k2v2: It's nice to see the 1" sensor gaining mainstream acceptance. When nikon introduced the 1" sensor everybody wailed how tiny it was. Now DPreview calls these "large sensor" cameras.

Most of the original super zooms spanned a range of around 18-200 (11:1), versus a more common zoom ratio of 3:1 or 5:1. The availability of a 24-200 (16.7:1) does not make an 18-200 or 24-200 any less a super zoom, only a later evolution of the trend.

Hugo808: Wow, I'd have thought the opposite would be the case with all the great cameras on the market!

We'd better get out there and spend some cash if we want to see an XT-2 or a D400. No point just talking about them.....

We were ready to spend money on a D400 years ago. Some of us have drifted off to M4/3 and Fuji, who knows where? But once those F-mount lenses get sold, there will be no returning. ...nor is the money really there any more.

I have a Sigma 70-200/2.8 and 1.4 TC, pre-stabilization era. For sports, the lens was used mostly on a monopod for several years. First the TC got a bit loose (floppy). When it would not autofocus reliably, I set the TC aside and continued to use the lens until it, too, became loose. Being on a limited budget, I decided tofix it the best I could. Presently a few wraps of electrical tape hold the main body together well, and ample superglue fixed the TC. The tape is just enough nuisance to keep me from using the tripod clamp though.

I'm pretty sure my habit of leaning on the lens while using the monopod caused the problem in the first place. Now that I hold it, it works fine and shows no more problems. I still think of the lens as pretty much bullet-proof, and it has really strengthened my right-hand grip! In the long run, I'm sure the mass of these lenses is the primary wear factor- and I wouldn't want the added complexity of internal stabilization, at least for my use.

jdhill66: Another situation where this technique is helpful is casual flash photography where near portions are too hot and far portions are too dark.

Not so, Abe,

The article might make me consider buying some extra software, but in fact, it pointed out things about software I already own that I have not taken advantage of. I appreciated the issues addressed by the author, even if this overall topic has to come up pretty often. It always helps to see alternate solutions compared side by side (and without my having to buy the software up front).

Thanks for the effort, Ellen.

feinschmecker: Is this the conclusion: "Buy this book on"?!?

@ Mr. Diallo,

What happened to, "The customer is always right?" Yes, we understand that reviews take a long time to do thoroughly, but the fact is that the feature articles, in particular, have grown increasingly fluffy. The recent article on shooting at the beach was just such a fluff piece, and DPReview of ten years ago would not have published many, if any, of those shots unless to use them as examples of what not to do. I will always be an amateur, but I have grown from the comments of the many capable and generally competent participants on this site in the past. I would certainly like to see it remain top notch.
